Of course, these are merely examples and are not intended to limit the embodiments of the present invention.

Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] See also Figure 1-2 As shown, this embodiment provides an escapement screw wrench, comprising a mounting tube 1, a rotating rod 2 rotatably disposed in the mounting tube 1 about its own axis, a wrench head 3 connected to the lower end of the rotating rod 2, a rotating handle 4 connected to the upper end of the rotating rod 2, at least two jaws 5 rotatably disposed on the mounting tube 1 and arranged around the outside of the wrench head 3, and a driving mechanism 6 disposed on the mounting tube 1 and used to drive the at least two jaws 5 to open and close relative to each other.

[0032] In this embodiment, the rotating rod 2 is arranged coaxially with the mounting tube 1, and both ends of the rotating rod 2 extend out of the mounting tube 1 respectively. The wrench head 3 is detachably mounted on the lower end of the rotating rod 2 so as to be replaced with different sizes as needed.

[0033] In this embodiment, the wrench head 3 is non-magnetic so as to be suitable for magnetic field limiting.

[0034] In this embodiment, an LED light 7 is provided on the wrench head 3 to provide lighting during operation.

[0035] See also Figure 2 As shown, at least two clamping jaws 5 are evenly spaced along the circumference of the mounting tube 1. The upper ends of the clamping jaws 5 are pivotally connected to the mounting tube 1, and the lower ends of the clamping jaws 5 are used to engage with each other to clamp the screw. In this embodiment, there are two clamping jaws 5, with an angle of 180° between them. The clamping jaws 5 are arranged horizontally relative to the rotation axis of the mounting tube 1 and perpendicular to the mounting tube 1.

[0036] The drive mechanism 6 comprises a connecting rod 61 rotatably mounted on the mounting tube 1 and a lifting handle 62 connected to the upper end of the connecting rod 61. The clamping jaw 5 is pivotally connected to the lower end of the connecting rod 61 via its upper end. Specifically, there are two connecting rods 61, each pivotally connected to the clamping jaw 5. The upper ends of the two connecting rods 61 are each connected to the lifting handle 62. The lifting handle 62 is higher than the upper end surface of the mounting tube 1, and the lower end surface of the mounting tube 1 limits the downward movement of the lifting handle 62.

[0037] See also Figure 1 As shown, the upper end of the rotating rod 2 extends upward from the mounting tube 1, and the rotating handle 4 is located above the lifting handle 62. The driving mechanism 6 also includes an elastic member 63 that is elastically arranged between the rotating handle 4 and the lifting handle 62 along its own elastic expansion and contraction direction. The elastic member 63 is used to provide an elastic restoring force to drive the lifting handle 62 to move downward and return to its original position. In this embodiment, the elastic member 63 is a compression spring mounted on the rotating rod 2.

[0038] The clamping jaws 5 have a clamping position and a release position. The connecting rod 61 is used to switch the clamping jaws 5 between the clamping and release positions by moving them up and down relative to the mounting tube 1. When the lifting handle 62 is pulled upward, the pair of clamping jaws 5 are relatively retracted. When the lifting handle is released, the pair of clamping jaws 5 move downward under the action of the compression spring, and the pair of clamping jaws 5 are relatively released.

[0039] By this arrangement, the clamping jaws 5 can cooperate with each other to clamp the screw, and can clamp the screw in advance during work to avoid the screw from falling during assembly and disassembly. In addition, even if the screw accidentally falls during assembly and disassembly, it can be picked up by the clamping jaws 5, and the cleaning difficulty is relatively low.

[0040] See also Figure 2 As shown, the clamping jaw 5 includes a pair of short rods 51 and long rods 52 connected in sequence and intersecting with each other. The clamping jaw 5 is rotatably connected to the mounting tube 1 at its corner. The clamping jaw 5 is rotatably connected to the connecting rod 61 via the short rod 51. The first rotation axis of the clamping jaw 5 relative to the mounting tube 1 and the second rotation axis of the clamping jaw 5 relative to the connecting rod 61 are parallel to each other. In this embodiment, the long rod 52 is connected to the short rod 51 at its upper end, and the clamping jaw 5 also includes a clamping portion 53 connected to the lower end of the long rod 52.

[0041] In this embodiment, the mounting tube 1 includes a tube body 11, a connecting seat 12 sleeved on the lower end of the tube body 11, and at least two through holes 13 evenly spaced along the circumferential direction of the mounting tube 1 and opened in the connecting seat 12. The short rods 51 are arranged in the through holes 13 one by one.

[0042] Specifically, an obtuse angle is formed between the short rod 51 and the long rod 52, with the wrench head 3 located inside this obtuse angle. A first shaft 121 is provided on the connecting base 12. This first shaft 121 forms the outer perimeter of the through hole 13 and passes through the connection between the short rod 51 and the long rod 52. The axis of the first shaft 121 serves as the first rotation axis. A second shaft 611 is provided at the lower end of the connecting rod 61. This second shaft 611 passes through the end of the short rod 51 away from the long rod 52. The axis of the second shaft 611 serves as the second rotation axis. The second shaft 611 is located between the tube body 11 and the first shaft 121.

[0043] See also Figure 2 As shown, the connecting rod 61 further includes an inverted U-shaped connecting member 612 for connecting the rod body and the second shaft 611 . The inverted U-shaped connecting member 612 is used to connect the two ends of the second shaft 611 extending out of the short rod 51 .

[0044] The working process of this embodiment is described in detail below:

[0045] When installing a screw, lift the lifting handle 62 to clamp the screw on the wrench head 3 through the clamping claw 5, then insert the mounting tube 1 into the device, rotate the rotating handle 4 to tighten the screw, then release the lifting handle 62 to loosen the screw, and then remove the mounting tube 1;

[0046] When removing the screw, insert the mounting tube 1 into the device, then pull up the lifting handle 62 to clamp the screw on the wrench head 3 through the clamping claw 5, rotate the rotating handle 4 to remove the screw, and then take out the mounting tube 1.

[0047] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
