The technical scheme of the utility model is further described in detail by the following specific embodiments in combination with the attached drawings:

example 1

As shown in fig. 1 to 4, a bottomless channel steel thread bushing assembling tool comprises a sleeve 1 and a pickup head 2 arranged in the sleeve 1, wherein the pickup head 2 is provided with a first end portion 21 arranged oppositely and a second end portion 22 connected with an external power shaft, two ends of the sleeve 1 are respectively provided with a first port 11 used for extending the first end portion 21 and a second port 12 used for extending the second end portion 22 out of the sleeve 1 or used for extending the external power shaft into the sleeve 1, external threads used for being in threaded connection with the bottomless channel steel thread bushing are arranged on the circumferential surface of the first end portion 21, a limiting hole 3 is obliquely arranged on the sleeve 1 along the circumferential direction of the sleeve 1, and a limiting column 4 connected with the pickup head 2 is arranged in the limiting hole 3. In this embodiment, when in use, the limiting post 4 is shifted to one side of the limiting hole 3 far away from the first end 21 (i.e. the limiting post 4 is located at the high side in the limiting hole 3), the bottomless channel steel wire thread sleeve is installed on the external thread of the first end 21 of the pick-up head 2, and the end surface of the first port 11 of the sleeve 1 is abutted against the end surface of the bottomless channel steel wire thread sleeve; an external power shaft is adjusted to be in a forward rotation state, the external power shaft is positioned at one side of a limiting hole 3 far away from a first end part 21, the external power shaft drives a pick-up head 2 and a sleeve 1 to rotate together when the external power shaft rotates, a bottom-groove-free steel wire tooth socket is assembled on a component to be assembled and tightened, the external power shaft is adjusted to be in a reverse rotation state, the limiting column 4 is installed in the limiting hole 3 inclined on the sleeve 1, the pick-up head 2 rotates reversely while driving the limiting column 4 to rotate towards one side of the limiting hole 3 close to the first end part 21 (the limiting column 4 leaves a high position and rotates towards a low position), the limiting column 4 enables the sleeve 1 to move in the direction far away from the bottom-groove-free steel wire tooth socket, a gap is generated between the end face of a first port 11 and the bottom-groove-free steel wire tooth socket, namely, the sleeve 1 can be automatically separated from the bottom-groove-free steel wire tooth socket in the reverse rotation process of the external power shaft, and the pick-up head 2 can automatically withdraw from the bottom-groove-free steel wire tooth socket, and (5) finishing assembly. It should be noted that the external power shaft may be an electric screw driver, or may be another power shaft, and the external power shaft may be detachably connected to the second end 22; the limiting hole 3 is communicated with the inner cavity of the sleeve 1. It should also be noted that the forward rotation of the external power shaft refers to the rotation direction of the external power shaft when the bottom-slot-free steel wire tooth socket is assembled on a component to be assembled and tightened.

Wherein the second end portion 22 is located in the sleeve 1, and an elastic member 5 for pretensioning the pick-up head 2 is arranged between the second end portion 22 and an inner end surface of the sleeve 1 remote from the first end portion 21. In the embodiment, the elastic member 5 is used for pre-tightening the pickup head 2, so that the problem that the pickup head 2 shakes during the process that the limiting column 4 moves from the side far away from the first end portion 21 to the side close to the first end portion 21 along the limiting hole 3 is avoided.

The elastic member 5 has a spring structure, one end of which abuts against the second end 22 and the other end of which abuts against the inner end surface of the sleeve 1. Can rely on spring structure's elasticity like this, carry out the pretension to pickup head 2, avoid spacing post 4 when removing in spacing hole 3, the problem that pickup head 2 rocked appears.

Wherein the free end of the external power shaft is inserted through the spring structure and connected with the second end 22. Therefore, the rotary power of the external power shaft can be transmitted to the pick-up head 2, and when the external power shaft rotates, the external power shaft drives the pick-up head 2 to rotate, so that the bottom-groove-free steel wire tooth socket can be assembled on a required accessory.

In addition, a threaded hole 6 is formed in the pick-up head 2, and the limiting column 4 is in threaded connection with the threaded hole 6. In the embodiment, the limiting column 4 is in threaded connection with the threaded hole 6, so that the limiting column 4 and the pickup head 2 can be conveniently mounted and dismounted; simultaneously, when assembling the no end channel-section steel wire facing to different specifications, dismantle spacing post 4 from picking up head 2, pull down picking up head 2 and change the picking up head 2 of different specifications (have the picking up head 2 of different external screw thread specifications) in following sleeve 1, can make this erecting tool adapt to the assembly work of the no end channel-section steel wire facing of different specifications.

Wherein, the second end portion 22 is provided with a mounting hole 7 for an external power shaft to extend into, and the mounting hole 7 is communicated with the threaded hole 6. In this embodiment, the external power shaft is inserted into the mounting hole 7, and since the mounting hole 7 is communicated with the threaded hole 6, when the limiting column 4 is in threaded connection with the threaded hole 6, the external power shaft can be stably connected with the second end 22 of the pick-up head 2 by the extrusion force of the limiting column 4 on the external power shaft.

In addition, a limit step 8 for abutting against the bottomless channel steel thread bushing is provided on the sleeve 1 near the first end 21 and on the first port 11 side. In this embodiment, the limit step 8 is located at the outer edge of the first port 11, and when the bottomless channel steel thread bushing is installed on the external thread, the end surface of the bottomless channel steel thread is abutted to the end surface of the limit step 8.

Wherein the outer diameter of the pick-up head 2 is adapted to the inner diameter of the sleeve 1. It should be noted that the outer diameter of the pick-up head 2 is preferably adapted to the inner diameter of the sleeve 1, and when the external power shaft drives the pick-up head 2 to rotate reversely, the pick-up head 2 rotates inside the sleeve 1, thereby avoiding the problem of shaking of the pick-up head 2.

In addition, the diameter size of the limiting column 4 is matched with the width size of the limiting hole 3. In this embodiment, when external power shaft counter-rotation, drive spacing post 4 rotatory, spacing post 4 removes in spacing hole 3, because the diameter size of spacing post 4 and the width size looks adaptation of spacing hole 3 for the both sides wall of spacing hole 3 all can contact with the global of spacing post 4, and the removal of spacing post 4 in spacing hole 3 is more stable.

Wherein the size of the second port 12 is adapted to the diameter of the external power shaft. In this embodiment, this facilitates the extension of an external power shaft connected to the pick-up head 2 into the sleeve 1 through the second port 12.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
