The male and female chuck spring self-locking shaft is in fact composed of a male and female chuck fixed to the object to be abutted against each other, a movable male and female chuck non-circular shaft and a self-locking urging spring 8. The movable convex-concave chuck non-circular shaft is a convex-concave chuck which is in face-to-face engagement with the fixed convex-concave chuck, the convex-concave chuck spring self-locking shaft can be a rigidly connected non-cylinder (such as a prism, an ellipse, a circular table, an embedded key cylinder and the like), the other end of the non-circular shaft chuck (the convex-concave chuck spring self-locking shaft) is provided with a spring stop baffle plate D which is fastened by a bolt, and the convex-concave chuck spring self-locking shaft can axially and smoothly move.

The liquid injection magnifier sheet shell 6 can be formed by one-time casting or blow molding, and can also be integrated into a whole by the involution, clamping, buckling or screw screwing of the upper surface and the lower surface through rubber rings. The specific material is transparent enough, drop-resistant, scratch-resistant, stable in chemical performance and light decay resistant, and can be properly balanced according to density, process simplicity, production difficulty, wide liquid injection affinity spectrum, cost and the like. The liquid is injected into the liquid injection table type magnifier base 1 and the liquid injection magnifier sheet shell 6, and the liquid is selected and chosen among purified water, distilled water, alcohol or other people according to a plurality of factors which are convenient to obtain, store, draw materials, have low price and are suitable for pursuing the target according to the basic front dike which is not deposited, has stable performance, does not generate chemical reaction, does not form harm to human health, is not corroded and the like.

As the magnifier frame base 4 and the transparent lighting frame 5 (the transparent lighting frame 5 is positioned on the magnifier frame base 4, the transparent lighting frame 5 can be provided with the patch light-emitting diode) are made of transparent organic glass or plastic, the radial additional dimension expansion is relatively not very outstanding, the edge thickness is slightly increased, and the external outline of the patch light-emitting diode is small, the product finally formed has no visual blind area while providing a huge observation visual field, and does not form excessive obstruction and restraint on operations such as welding and the like, thereby improving the function that the prior similar product forces a user to stretch the neck to be tired after long-time work and possibly generate occupational diseases of cervical vertebra infection.

The one-way surface light source characteristic of the patch light-emitting diode increases the conical angle of the illumination area on one hand, is beneficial to creating a shadowless effect, and on the other hand, does not generate dizzy stimulation to the eyes of an operator. The illuminating light-emitting diodes are distributed and uniformly arranged according to groups, and the closing and turning-off control switches of each group are arranged on the frame base 4 of the magnifier.

In essence, the final manufacturing materials of the table type magnifier base 1, the magnifier lower cantilever 2 and the magnifier upper cantilever 3 are not set deliberately, and the table type magnifier base, the magnifier lower cantilever 2 and the magnifier upper cantilever 3 can be selected preferentially among iron sheets, aluminum alloys, nylon, coated organic glass, plastics and the like under the promotion of the goals of production, sale, profit and the like as long as the table type magnifier base is coordinated with other parts of the whole product, adapts to the trend of the main body of the era and meets the purchasing psychology of customers. As for the beautification and decoration of the shape, the size and the appearance, the key points are mainly considered as stable, light, small, heavy, atmospheric, durable, convenient to manufacture and produce and the like, so that the equipment is not over biased and extreme, and strives to coordinate, give consideration to and optimize the whole.

Fig. 3 shows a solder mounting bracket, which is composed of a circuit board mounting bracket 11, leg bolts 12, a front circuit board mounting base 14, a rear circuit board mounting base 13, front and rear mounting base connection screws 15, and front circuit board base urging springs 16. The circuit board clamping support 11 is arranged in front of and behind the circuit board clamping support, plays the role of the base of the whole tin welding clamping support, and is symmetrically provided with four supporting leg bolts 12 in front of, behind, on the left side and on the right side of the bottom of the circuit board clamping support. By adjusting the leg bolts 12, the height of the circuit board clamping base can be raised and lowered, and the clamped circuit board plane can be leveled or inclined, so that soldering can be performed more easily. In addition, the device can be properly matched with peripheral devices such as a desktop magnifier and an inverted plug-in lifting bracket, so that manual soldering is more convenient, light and easy to evolve. The front circuit board clamping base 14 and the rear circuit board clamping base 13 realize the horizontal pushing clamping and bearing of the circuit board under the cooperation of the front and rear clamping base connecting screw 15 and the front circuit board base pushing spring 16. Due to the bilateral symmetry, balance and parallel distribution characteristics of the front and rear clamping base connecting screw rod 15 and the front circuit board base pushing spring 16, the stress is mainly expressed as backward horizontal pushing when the circuit board is clamped and loaded. In order to ensure the normal performance of the flat-pushing performance, at least two sets (one set for each of the front and rear clamp base connection screw 15 and the front circuit board base pushing spring 16) should be provided for the combination of the front and rear clamp base connection screw 15 and the front circuit board base pushing spring 16, and the increase is not recommended because it is not particularly obvious although it is slightly helpful. In addition, since the front and rear circuit board clamping bases have a long parallel structure, clamping can be relatively firmly performed even if the circuit board is not completely regular rectangular in shape. The bent pawls (notches (11-1)) on the clamping bases of the front and rear circuit boards firmly clamp the circuit board and prevent the circuit board from sliding and laterally moving, and the clamping and unloading of the circuit board can be easily finished only by pushing and pulling. Meanwhile, the circuit board cannot be damaged. By adjusting or replacing the front and rear clamping base connecting screw rod 15 or the front circuit board base pushing spring 16, the clamping tightness degree of the circuit board can be changed in a large range, the circuit board clamping device can adapt to the changes of the external dimensions of circuit boards with different specifications at will, and the requirements of different customer communities and temporary individual operation are met.

Similar to the above, the circuit board clamping bracket 11, the front circuit board clamping base 14 and the rear circuit board clamping base 13 do not have to pursue strength, beauty and perfection excessively, and only need to meet the overall pursuit target and ensure that the normal use is not influenced and the psychological bearing scale of the consumer is matched. The present invention is more intended to select the most common and cheap angular and groove-shaped metal or plastic in the market, and the preset target is achieved on the basis of slightly modified machining. However, for the purpose of preventing the front half portions of the front circuit board clamping base 14 and the circuit board clamping bracket 11 from pitching, shifting and tilting, the same object should be achieved by providing a cured bushing on the side (left or right side of the component as shown in fig. 3) where the respective connecting screws 15 penetrating the front and rear clamping bases increase their thickness appropriately (that is, increase the thickness in the left-right direction as shown in fig. 3), or on the side where the assembly of peripheral parts is not hindered. At the rear end of the soldering clamping bracket, because the nuts on the connecting screw rods 15 of the front and rear clamping bases are adopted for tightly screwing and locking, the problems of pitching, shifting and inclining do not exist between the rear part of the circuit board clamping bracket 11 and the rear circuit board clamping base 13, and further special consideration is not required in design. With regard to the shape of the front board base urging spring 16, a trade-off may be made between the tower spring and the cylinder spring. The two types of springs have the advantages and the disadvantages respectively, the former has a large moving range but has very different end face size, so that a plurality of special requirements need to be considered and met, and the latter is almost just opposite, so that the overall consideration and the comprehensive measurement are needed. But more importantly, the user can adapt to the individual needs of different users by adopting different modes instead.

In physical structure, the soldering clamping support and the table type liquid injection folding lighting magnifier are relatively independent, and can be selected or selected and replaced by specific individual types according to actual operation requirements. Generally, the soldering clip support should be located inside the arc area of the base under the desktop liquid-filled folding lighting magnifier, both of which are commonly placed on the work platform or desktop.

All people who have experienced manual soldering experience are well aware of that the people often lose the experience during soldering, sometimes want help of others, and more often are limited to various factors and cannot meet the needs. For manual soldering, an operator needs to hold a soldering iron to solder, feed solder wires, clamp components or hold a circuit board without slippage, and the like, and all the things are completed with one hand, so that people have to worry about seeking various ingenious ideas, and can only replace the needs of the operator with the cost of time, quality and material waste in more times. The limitation belongs to the chronic disease which cannot be eliminated in the field for a long time, and how to break through the problem is the primary target pursued by the patch pressing cantilever 17.

As shown in fig. 3 and 4, the solder clip bracket has a more important mission than the clamping and carrying of the circuit board, which is to prevent the small, light and movable chip-type components from slipping and twisting during the welding process. Especially, like a small-sized multi-fine pin integrated circuit chip, the integrated circuit chip slightly deviates from the set preset position and posture, so that the device arrangement is uneven and the product attractiveness is affected by a light person, and annoying insufficient soldering, short circuit and subsequent devices are easily prevented from being placed smoothly by a heavy person, and even the whole work is completely scrapped. Even if the scrap level is not complete, finding and removing cold solder joints and insignificant short circuits is a very annoying, headache, and time consuming task. It is the most fundamental way to go out and pursue the goal of avoiding or eliminating it completely in the bud. On the back circuit board clamping base 13 of the back end of the soldering clamping bracket, several vertical cantilever supporting bolts 19 fastened by nuts are arranged according to the requirement, each cantilever supporting bolt 19 is sleeved with one or more groups of patch pressing cantilevers 17 clamped up and down by a cantilever clamping shaft sleeve 18 from bottom to top, and the top end of each group of patch pressing cantilevers is pushed down by a cantilever pressing spring 20. The patch pressing cantilever 17 is actually a flat or slightly bent rigid spring which is rich in elasticity and provided with a long hole in the middle, a boss is specially arranged below the tail end of the spring, and the boss is configured to press and hold the patch component so as to prevent possible slippage and torsion. According to the size, the outline and the adaptability of the patch component, the height, the shape, the projection size and the like of the boss are reasonably set. Similarly, the material of the boss should be balanced, and the important criteria for choosing between hard metal and soft rubber, cork or silica gel depends on not only the material characteristics, durability, processing convenience, cost and purchasing convenience, but also the allowable degree of scratch and damage to the pressed object, and the anti-ironing and deformation characteristics of the soldering iron head once touched. The pressing and holding principle of the patch pressing cantilever 17 on the patch element is that the patch pressing cantilever 17 is tightly buckled together by the bosses of the upper and lower cantilever clamping shaft sleeves 18 passing through the strip holes face to face, and under the pushing of the cantilever pressing spring 20, the former can only be pulled and pushed along the orthogonal direction of the bus bar of the cantilever supporting bolt 19 under the constraint of the bosses of the cantilever clamping shaft sleeves 18, but can not rotate around the bus bar of the latter or generate head raising and bow.

The patch hold down cantilever 17 cluster should be batch prepared, soldered, and removed in the way of high, low, evenly distributed, and holding the components at most, with the guidance of convenient arrangement, removal and no obstacle to fixed-point observation and soldering in the same posture, according to the principle of no mutual interference and conflict. Therefore, the method not only can weld a batch of components as many as possible, but also effectively eliminates the times and time for taking tools and components, and is beneficial to improving the working efficiency and reducing the labor intensity. And the probability of taking wrong components can be greatly avoided, and the components can be taken in batches, so that the components are more easily taken in a concentrated manner and are classified according to categories and items in contrast, and the inertia of thinking caused by fatigue of people in long-time repetitive work can be overcome conveniently.

Manual soldering cannot completely eliminate the use of direct-insertion components, and although the current trend is that patches are used more and more frequently, the direct-insertion components still occupy a large space to a great extent. Straight cards are actually soldered a lot positively on a circuit board, but upside down soldering is more common, especially in the case of single-sided circuit boards. The most outstanding difficult problems of the inverted welding of the straight plug-in are gliding, falling and deflection, and the difficulty of solving the troublesome problem is further improved due to the reasons that other welded parts have different heights, circuit board shielding and narrow space, fingers and tools are inconvenient to hold, clamp, the surplus sizes of pins of the bonding pads are different, the angles of the pins are changed, the weight of components is varied, and the like.

As shown in fig. 5, the reverse plug-in lifting support is composed of a base 21, a bottom bolt 22, a lower connecting bolt 23, an upper connecting bolt 25, a supporting spring 24 and a reverse plug-in lifting support frame 26, for multiple purposes of coordination, beauty, practicality and the like, the bottom bolt 22, the lower connecting bolt 23, the upper connecting bolt 25 and the supporting spring 24 should be symmetrically arranged in the front, back, left and right directions, and the base 21 and the reverse plug-in lifting support frame 26 are mainly shaped as a rectangular flat plate. In order to reduce the dead weight, through holes or blind holes are uniformly formed on the base 21 and the inverted plug-in lifting support frame 26 according to a certain pattern. The base 21 and the reverse plug-in supporting frame 26 are made of selected materials, and are made of the most common and cheap angular and groove-shaped metal or plastic in the market through simple mechanical processing such as injection molding and drilling, like a circuit board clamping bracket and a front and rear circuit board clamping base of a soldering 4 clamping bracket. In order to comprehensively realize the purpose that the reverse plug-in lifting bracket is widely suitable for different devices, firstly, the adjusting scale of the bottom bolt 22 is properly set for various operations; secondly, the shape, the bus diameter, the steel wire radius, the hardness and the like of the supporting spring 24 need to be considered comprehensively; thirdly, the proper and proper shape and size of the base 21 and the inverted plug-in lifting support frame 26 must be determined according to the restriction factors of the shape of the circuit board, the distribution position of the batch welding direct plug-in devices, the size of the devices, the weight and the like. However, when a specific design principle of the reverse plug-in lifting support is finally formulated, the principle of use should be followed, that is, the device is small first and then large, short first and then high, heavy first and then light, and the device is in order according to the category, and the layout of the circuit board is internal first and external first, dense first and then sparse first, difficult first and easy later, so that the pressure is reduced to the maximum extent, and the characteristics of practicability, high efficiency, low error and weak labor intensity are enhanced.

Generally, the flip-chip lift bracket is a functionally extended attachment to the solder clip carrier bracket. In other words, while the use of the reverse plug-in lifting bracket is necessary, the use of the soldering clip bracket is inevitable, and the latter can exert the limiting effect by separating from the former, but the former can hardly play the independent function by separating from the latter. That is, if the latter is not used, the former will almost immediately lose its value and significance. In most cases the flip-chip lifting brackets are located below the solder clip brackets, but may be protruding at particular times, even though not exclusively, intentionally assisting each other by arranging a plurality of flip-chip lifting brackets outside the projection area of the solder clip brackets to achieve unexpected functional effects. No matter how different the specific use is, the basic characteristic is that the reverse plug-in lifting bracket and the soldering clamping bracket are always placed on a working platform or a desktop together.

In conclusion, the utility model realizes the integral folding, extension, contraction, mirror angle adjustment and setting pose locking of the desk magnifier; by opening and closing each switch as required, the grouped lightening of the light emitting diodes embedded in the magnifier frame base and the transparent frame cluster is achieved; the table magnifier is stably and normally used by injecting transparent liquid into the magnifier base and the liquid injection magnifier shell and blocking the liquid injection hole, and the pursuit of portability of carrying and carrying is met by discharging the liquid; the tin welding clamping support achieves the effects of flexible flat pushing in a large size range, lossless clamping and circuit board bearing under the combined action of the circuit board clamping support, the support leg bolts, the front and rear circuit board clamping bases, the front and rear clamping base connecting screw rods and the front circuit board base pushing spring; the pressing cantilever and the cantilever clamping shaft sleeve which are arranged on the vertical upright post bolt at the rear end of the tin welding clamping support in a group are pushed by the cantilever pressing spring to firmly press and hold the paster device, so that the paster device cannot slide or twist during welding; the reverse plug-in unit lifts the support frame, the supporting leg bolt, the footing bolt, the upper connecting bolt, the lower connecting bolt and the supporting spring to cooperate together, not only lifts reverse plug-in elements with different sizes and heights, so that welding is lighter and more handy, but also the reverse plug-in unit and the tin welding clamping support together further enhance the capability of adapting to various special requirements, thereby greatly improving the working efficiency, improving the welding quality and reducing the labor intensity. The utility model discloses a structure is succinct, reasonable, the combination is dexterous, the practicality is outstanding, can satisfy the general requirement to the manual soldering such as small batch production product trial-manufacturing, electrical apparatus maintenance, also can accelerate the technical ability promotion of staff training, student's innovation experiment, preparation. The low processing technology threshold, the low cost and the easily selected raw material market space all contribute to the very easy development into novel products with wide prospects.

From the foregoing, it can be seen that the utility of the present invention is very obvious. Firstly, the three parts of the table type liquid injection folding lighting magnifier, the tin soldering clamping bracket and the inverted plug-in lifting bracket which form the manual tin soldering magnifying lighting clamping combination table are relatively independent, any one or two parts are lacked, and the rest can still exert certain original efficiency under the condition of reducing the performance. Secondly, the wide-range self-adaptive capacity of the soldering clamping support and the inverted plug-in lifting support greatly improves the free response of different requirements and conditions. Finally, the seriation and multi-specification configuration of the soldering clamping support and the inverted plug-in lifting support further enriches the complex problem handling capacity of the whole structure, thereby fundamentally enhancing the market competition level of the final product and the degree of satisfaction of the individual requirements of different groups.
