Description

Screw head into the depth limit sleeve structure

This creation is related to a screw-in depth limit sleeve structure of a screwdriver head, and more specifically, it can be used in any combination of adapters for excellent convenience, practicality and height. The novel creation of economic benefits.

Press, as shown in the seventh figure, is a stereoscopic schematic diagram of a special efficiency screwdriver head 10 with a defined penetration depth, which is known from the figure, which is a sub-head 11 and a limit sleeve. 12 is fixedly integrated, and the tip end segment 13 of the driver bit 11 is just outside the limit sleeve 12, after which the special efficiency driver head 10 can be inserted into the third figure or the fifth figure. The various adapters 30, 40 are used to rotate the screw workpiece 36. In addition, it must be noted that the force applying shaft ends 32, 42 of the adapters 30, 40 are generally provided with a power tool ( That is, the electric or pneumatic screwdriver, which is not shown in the figure), is used for plugging. The power factor of the power factor is stronger and the speed is faster. Therefore, the presence of the limit sleeve 12 must be prevented to prevent the screw workpiece 36 from being excessively screwed. Damage to the item being screwed.

At first glance, these "special performance starter heads" 10 seem to be extremely practical and simple, and indeed achieve the intended use; however, in fact, as previously mentioned, the power tools have strong torque and fast speed, making the screwdriver The tip end section 13 of the head 11 is often quickly damaged by various external factors such as improper operation, natural wear, accidental impact or excessive load, and thus is inconvenient to be used again. At this time, although the limit sleeve 12 may be intact, The screwdriver head 11 that is consolidated into one cannot be used, so that it can only be discarded and replaced without any other method. Conversely, if the limit sleeve 12 is damaged and it is lost, it should be used effectively. It can be seen that the conventional special effect screwdriver head 10 does not meet the reasonable expectations of the user in terms of economic efficiency.

Therefore, in view of the above facts, the creator has been familiar with the industry for many years. Experience, active research and development, this creation has to come out early; therefore, it is mainly focused on the use of the limit sleeve and the starter head so that it will not be discarded due to the destruction of the screwdriver, and thus strengthen The economic benefits, at the same time, make the limit sleeve free to be combined with various adapters to enhance its practical value. It is the main purpose of this creation.

Therefore, this creation refers to the "starter's screw into the depth limit sleeve", which is mainly composed of a cylinder, a card bead, a ring and a magnetic component, and the axis of the cylinder To the graded through hole to cover the outer circumference of a joint, and the card bead can be inserted into the corresponding ring groove of the adapter to generate a certain degree of locking effect; After being inserted into the working socket of the adapter, the tip end of the screwdriver head will just extend out of the barrel, so that the screw workpiece can be assembled and the magnetic member can be properly adsorbed to make the screw The workpiece does not fall off easily, and accordingly, the limit sleeve can perform its intended limit function to prevent excessive screwing of the screw workpiece.

In order to further understand the technical means and structural features of this creation, we will cooperate with a number of drawings to elaborate on the following: First, please refer to the first, second, third and fourth figures to see the structure of the creation and A schematic diagram of a preferred use state, as shown in the figure, the limiting sleeve 20 comprises: a barrel 21 having a columnar body with an axial-level through-hole 22 and an outer wide section 23 at the front end. a groove 25 of a bead hole 24 is formed on the circumferential surface of the rear end; a card bead 26 is placed at the bead hole 24 of the barrel; a ring 27 is inserted into the slot 25 of the barrel 20 to position the card bead 26; a magnetic member 28 is formed into a ring shape The body is fixed at the front edge of the stepped through hole 22 of the outer wide section 23 of the barrel body 20.

Yes, by the composition of the above components, it will be able to cover the outer circumference of a joint 30 by the through-hole 22 of the barrel 21, and the card bead 24 will be able to be inserted into the adapter 30. Corresponding to the ring groove 31, a certain degree of locking action is generated; after the screwdriver head 33 is inserted into the action socket 34 of the adapter 30, the action tip end 35 of the driver head 33 will just extend out of the barrel 21. In addition, the screw workpiece 36 can be applied in combination, and the magnetic member 28 can be appropriately adsorbed so that the screw workpiece 36 does not fall off easily, and accordingly, the limiting sleeve 20 can exert its intended limit. The position acts to prevent excessive screwing of the screw workpiece 36 as a feature.

In other words, when the tying head 33 is damaged at any time, we can only continue to use the screwdriver head 33, and the limit sleeve 20 shown in this creation can be continuously extended. There will be no inconvenience or trouble with the screwing operation.

For the same reason, please refer to the fifth and sixth figures. It shows that this creation can also be applied to another use state of the special adapter 40 which is more commonly used. As can be seen from the figure, it can also be borrowed from the cylinder. The 21-type through-hole 22 covers the outer circumference of the special adapter 40, and the card bead 24 can be inserted into the corresponding ring groove 41 of the adapter 40 to complete the assembly and can be smoothly completed. Use it to make it more highly practical.

Of course, since the width of the ring grooves 31, 41 of the adapters 30, 40 is slightly larger than the exposed contact surface of the ball beads 26 (that is, the contact portions of the two have appropriate clearances), the screwdriver head 33 acts on the tip end portion 35. The exposed extension length will be automatically adjusted slightly by the depth of the head end of the screw workpiece 36 (ie, moderate adjustment within the tolerance dimension), and the automatic adsorption positioning of the magnetic member 28 makes it suitable for various specifications. Various screw workpieces 36 within the size and achieve the desired screw depth limit performance; further, the limit sleeve 20 described in the present invention can be detached at any time and is suitable for various types of adapters 30 of corresponding specifications. 40, and therefore will not be restricted by the application object. In other words, the creation of the adapter 30, 40 can also be used with this creation, unless it affects the effective use of the adapters 30, 40. Use without any hindrance. In addition, the working sockets 34 of the adapters 30, 40 are adapted to be plugged into various types of screwdriver heads 33 (such as hexagons, a word, a cross, a meter, etc.). Without any restrictions on use.

Looking at the above, before the application, the creation of this creation has not only been found in similar products and related publications, but also has the practical value and positive benefits of "new" and "progress". Cheng has already met the application requirements of the new patent, and it is reasonable to obtain The protection of the patent law, 提出 apply in accordance with the law.
