Description of the new model: [Technical field to which the new model belongs] This creative department is related to auto repair tools, especially about the improved structure of a type of drive screw for auto repair. [Prior art] Please refer to the first figure, the hydraulic part (1) of the conventional auto repair tool generally has a tubular body. IH2) 'The upper and lower sliding pads ⑶⑷ are separated from each other and arranged in the pipe holes of the body (2)', and a proper fluid (5) is accommodated therebetween, and the coaxial screw is arranged on the body The driving screw (6) at the end pushes the upper slide (3), so as to press the slide pad (4) through the fluid (4) and displace it. It is the conventional technical content. In applications, when the resistance value exceeds the range that its internal components can withstand, the user still strongly applies the external driving force, which causes the sliding pads (3) (4) and other reasons. There are zero groups made of rubber material f, which cause improper damage caused by bursting, forming the grip body (5). 'These defects have not yet been conquered by the disclosed technology. [New content] _ The main purpose of this creation is to provide an improved structure of the driving screw of the hydraulic parts for auto repair. It can prevent the internal parts of the female parts for auto repair from being damaged by excessive force. Another purpose of this imagination is to provide an improved and structured drive screw for oil pressure parts used in auto repairs. Parts and components damaged by overload are easy to replace and facilitate maintenance. · Another objective of Pihan is to provide a modified structure of the driving screw of the hydraulic parts for auto repair. The driving external force applied when the maximum load has been reached can be properly blocked to avoid structural damage. Its damaged. M265169 Margin, in order to achieve the above purpose, the improved structure of the driving screw of the hydraulic parts for auto repair provided by this creation includes a shaft with a-predetermined length;-drive_, which is on one end of the shaft of the shaft , And its characteristic is that it also includes a low torque bearing part, which can bear the torque is lower than the torque that each shaft and drive head can withstand, and it is located in the drive head and the shaft -A predetermined position between the ends for transmitting an externally applied force on the driving head to the rod. [Embodiment] In the following, the three preferred embodiments of the present invention will be given in conjunction with the drawings for further explanation. Among them, the first figure is a cross-sectional view of conventional techniques. The first figure is an exploded perspective view of the first preferred embodiment of the present invention. The third figure is a three-dimensional appearance view of the first preferred embodiment of the present invention. The fourth figure is a cross-sectional view of the first preferred embodiment of the present invention along the direction of the third figure 4-4. The fifth diagram is the first preferred embodiment of the present invention in which the low torque receiving portion eliminates excessive torque. The sixth figure is a cross-sectional view of the second preferred embodiment of this creation. The seventh figure is a cross-sectional view of the second preferred embodiment of the present invention along the direction of the sixth figure 7-7. The eighth figure is a state diagram of the second preferred embodiment of the present invention to eliminate excessive torque with the low torque receiving portion. The ninth picture is a sectional view of the third preferred implementation of this creation. The tenth figure is a cross-sectional view of the third preferred embodiment of the present invention along the direction of the ninth figure 10-10. The eleventh figure is a schematic diagram of the third preferred embodiment of the present invention to use the low-torque receiving portion to eliminate excessive torque. M265169 The improved structure of the drive screw of the oil cake made in the "preferred embodiment" of the first "preferred embodiment of the acid" (_ by-the shaft, a drive head (30) and a low torque bearing The shaft is a rod-shaped body of an appropriate length and externally threaded, and the drive head (30) is-fixed to the shaft of the shaft and an end. The hexagonal outline of the cap sleeve, however, as each of the shafts (collection of heads in the technical field to which this creation belongs is already a known technical content, it is no longer redundant. 3_ Chu is formed by Lai turned around (2_ Responding to the corresponding miscellaneous equipment of the Lintolulu, which is to reduce the strength of these parts to reach 卩 + low her tolerance range to less than each Ju__) and the shooter. The improved structure of the drive screw of the oil repairing hydraulic part is a direct replacement for Xi when it is used. The hydraulic pressure lever L) is operating at a certain degree of privacy and the resistance value of the text force rises sharply. The torque continuously applied from the outside via the drive head (30) will exceed the low torque. The range that the receiving part (30) can withstand. At this time, the low torque receiving part (30) protects the internal composition of the auto repair oil pressure piece (50) in a breaking manner (as shown in the fifth figure). In order to avoid damage to the internal components, the drive screw ⑽ can be directly replaced with a new one, which is convenient and easy to maintain. Again, as shown in Figure 6 to Figure 8, the second preferred embodiment of this creation There are two differences between the improved structure of the drive screw (10,) of the hydraulic parts provided in the first embodiment and the one disclosed in the first preferred embodiment. One is that the drive head (30,) is only placed on the One end of the shaft of the shaft (20,) is not fixed as in the first embodiment, and the other is that the low torque receiving portion (40,) is a bolt with a small outer diameter, and The bolt shaft is perpendicular to the shaft of the shaft (20,). 6 M265169 is installed on the shaft of the shaft (20), and the external surface of the shaft (20) is used to make the surface between the end and the hybrid (30 '). The driving head (3〇,) is connected to the Soviet Union. The low torque torque (4Q,) is transmitted by the plug, so that the shaft (20,) transfers the torque generated by the external force plus the low torque. The torque bearing part _ can be cracked, 'two the shaft (2σ) is connected to the discontinuity (30 "on the shaft loses butterfly __,), Qin bribes the drive head, ▲ L piece on the shaft as idle That is, as shown in the seventh and eighth figures. Miscellaneous 2 ㈣ autumn pictures to tenth-riding show, in the third preferred embodiment of the creation of ~ L oil pressure member drive screw improved structure (1Q ,, ), Its structure is different from the one disclosed by the first Shi: There are two :, said that the 5 Hai drive Shuo (30 ") is slightly tubular, and coaxially sleeved on the shaft (20 ,,). The cup shaft & up 'can be used for-engagement and-jump inspection-move. The other is related to the low torque receiving part (40 ,,) in this embodiment is not as the two embodiments disclosed above. Damage the fixed parts to achieve the whole thread, and the non-destructive way is the one, in detail, that is, the low torque receiving part (40 ,,) has a ring block "), coaxially and vertically fixedly installed on The inner pipe hole wall of the driving head (30 ") has a central ring hole and is sleeved on one end of the shaft of the shaft (20"). At least a pair of grooves (42 ,,) are recessed in the hole. Ring block ⑷ ") On the torus, a pair of bar-shaped bumps (431 ") formed on the shaft (20 ,,) by bolts (43") are corresponding to the pair of grooves (42 ,,). 'And when the driving head (30') is located at the engaging position, it can be engaged with each other correspondingly, so that the external force applied to the driving head (30 ,,) can drive the shaft ( 20 ,,) is rotated, a retaining body (44 ,,) constituted by a coil spring is coaxially sleeved on the shaft (20 ,,), and the lower end is abutted against the top of the ring block (41 ,,) On the side ring surface, the upper end is M265169, which is positioned by-clasps (45 ,,) attached to the end of the shaft (2〇 "), so as to provide appropriate elastic force to maintain restraint of the drive head (30, ,) Is located at the embedding position. With the composition of the above-mentioned components, when an external force is applied to the low-torque receiving portion (40 ") to generate an excessive torque, it is blocked by the positioning force provided by the maintaining body (44 ,,). Torque, _direction_ the swivel (44 ,,) and tighten the spring, such as-come, each should be recessed,) and the embedded wire between the bumps (431 ,,) has lost its resolution. , Causing the driving head (30 ,,) to idling on the shaft (2〇 ") (see the eleventh figure of the second household) 'in order to effectively protect the auto repair oil pressure 撃") Overall, in addition to eliminating the need to replace the specific parts of the previously unveiled two-case embodiment, the person who asks for special explanations is required to be 'Ben Weicai, and it can reach the shooter_trace bearing section (40 ,,) The range of the force, there are two ways-to control the original elasticity of the maintaining body (44 ,,), that is, by selecting different elasticity of the elastic body for the maintaining body (44 ,,), and- Then the position of the retaining body (44 ") is controlled by changing the setting position of the deduction") to achieve the effect of adjustment. As for the position of the film (45 "), it should only be Like those familiar with this technology could degenerate into a technical feature which is not a creation of, this material again redundant Chen. < Brief Description of Drawings > The first drawing is a sectional view of a conventional technique. ^ The second figure is a three-dimensional exploded view of the first preferred embodiment of this creation. = Three pictures are the three-dimensional appearance of the first preferred embodiment of this creation.
