DETAILED DESCRIPTION

[0027] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 , 3 4. The utility model provides a novel anti-slip wire wrench, including a wrench body 1, an axle pin 2, a fixed plate lip 3, a movable plate lip 4, a worm 7, an adjustment rail groove, and an adjustment through groove. The axle pin 2 is slidably sleeved in the adjustment rail groove, and the worm 7 is movably sleeved in the adjustment through groove. The fixed plate lip 3 is fixedly connected to the top of the wrench body 1, and the movable plate lip 4 is fixedly connected to the top of the axle pin 2. A slide groove connected to the adjustment rail groove is opened on the front of the wrench body 1, and a pressing button assembly 5 is arranged in the slide groove. The pressing button assembly 5 is fixedly connected to the front of the axle pin 2, and the pressing button assembly 5 cooperates with the wrench body 1 to realize the position positioning of the axle pin 2. The outer sides of the fixed plate lip 3 and the movable plate lip 4 are provided with V-shaped grooves;

[0029] The fixed plate lip 3 and the movable plate lip 4 have the same structure. The movable plate lip 4 includes a main plate lip 41 and a connecting platform 42. A square insert 43 is fixedly connected to the top of the connecting platform 42. A square insert groove is provided at the bottom of the main plate lip 41. The square insert 43 is embedded in the square insert groove.

[0030] The pressing button assembly 5 includes a threaded column 51 and a pressing button body 52. ​​The threaded column 51 passes through the sliding groove of the wrench body 1 and is fixedly connected to the shaft pin 2. The pressing button body 52 is threadedly sleeved on the side wall of the threaded column 51, and the pressing button body 52 is located on the front side of the wrench body 1.

[0031] Reference Figure 4 A plug shaft 44 is fixedly connected to the top of the square embedding block 43, and a pin hole connected to the square embedding groove is arranged inside the main board lip 41, and an anti-slip ring 46 is fixedly connected in the pin hole. The top of the plug shaft 44 passes through the inner cavity of the anti-slip ring 46 and enters the pin hole. An anti-slip disk 45 is fixedly connected to the top of the plug shaft 44. The diameter of the anti-slip disk 45 is larger than the inner diameter of the anti-slip ring 46. Through the cooperation of the anti-slip disk 45 and the anti-slip ring 46, the upward movement distance of the main board lip 41 can be limited, thereby preventing the main board lip 41 from falling off and being lost.

[0032] Reference Figure 4 A magnetic disk 47 is fixedly connected to the top of the pin hole of the mainboard lip 41, and the magnetic disk 47 is magnetically connected to the anti-detachment disk 45. Through the magnetic cooperation between the magnetic disk 47 and the anti-detachment disk 45, a certain tightening effect can be achieved between the mainboard lip 41 and the connecting platform 42, thereby preventing the mainboard lip 41 from being too loose on the top of the connecting platform 42.

[0033] Reference Figure 5Sand-proof covers 6 are fixedly installed on the front and back sides of the wrench body 1 at the adjustment grooves. The two sand-proof covers 6 are used to close the adjustment grooves of the wrench body 1. By setting two sand-proof covers 6 to close the adjustment grooves, the connection between the shaft pin 2 and the worm 7 can be prevented from being directly exposed to the outside, thereby preventing external mud and sand from being embedded in the connection between the shaft pin 2 and the worm 7 to cause a jam, so that the wrench has a certain anti-mud and sand effect.

[0034] Reference Figure 5 A transfer groove is arranged inside the wrench body 1, in which a transmission assembly 9 is arranged inside the transfer groove, one end of the worm 7 penetrates into the transfer groove and docks with the transmission assembly 9, and a knob 8 is arranged on the front side of the wrench body 1, and the knob 8 penetrates into the transfer groove and docks with the transmission assembly 9. In order to ensure the convenience of adjusting the spacing between the fixed plate lip 3 and the movable plate lip 4 under the sealing effect of the two sand-proof covers 6, the knob 8 and the transmission assembly 9 are cooperated, and when the knob 8 is rotated, the worm 7 is driven to rotate under the transmission effect of the transmission assembly 9, thereby achieving a quick adjustment effect.

[0035] Reference Figure 6 The transmission assembly 9 includes a passive bevel gear 91, an active bevel gear 92, and a rotary rod 93. The passive bevel gear 91 is fixedly connected to one end of the worm 7. The rotary rod 93 is movably sleeved in the transfer groove of the wrench body 1. The active bevel gear 92 is fixedly connected to the side wall of the rotary rod 93. The passive bevel gear 91 and the active bevel gear 92 are meshed with each other. The knob 8 is connected to the positive end of the rotary rod 93. When the knob 8 is rotated, the rotary rod 93 is driven to rotate. Under the meshing effect of the passive bevel gear 91 and the rotary rod 93, the worm 7 can be driven to rotate, thereby achieving the transmission effect of the transmission assembly 9.

[0036] Reference Figure 7 The button body 52 includes a main button body 521 and a rotary cover 522. The main button body 521 is threadedly sleeved on the side wall of the threaded column 51, and the rotary cover 522 is movably sleeved on the back end of the side wall of the main button body 521. The threaded column 51 passes through the inner cavity of the rotary cover 522. The rotary cover 522 is set as a contact piece between the button body 52 and the wrench body 1. When the button body 52 rotates and moves to contact the wrench body 1 to generate friction, the rotary cover 522 is fixed under the influence of the friction, and the main button body 521 can still rotate alone and continue to cooperate with the threaded column 51 for advancement. In this way, the friction between the button body 52 and the wrench body 1 can avoid limiting the maximum rotation angle of the button body 52, so that the button body 52 can press the wrench body 1 to the greatest extent.

[0037] Reference Figure 7 The inner wall of the rotary cover 522 is fixedly connected with an anti-slip ring 523, and the side wall of the main button body 521 is provided with an annular positioning groove, and the anti-slip ring 523 is movably sleeved in the annular positioning groove. By providing the anti-slip ring 523 and the annular positioning groove of the main button body 521, the rotary cover 522 can be prevented from falling off the side wall of the main button body 521.

[0038] The working principle of the utility model is as follows: when in use, after adjusting the fixed plate lip 3 and the movable plate lip 4 to a suitable spacing, the pressing button body 52 is rotated to engage with the threaded column 51, so that the pressing button body 52 moves toward the wrench body 1 until the front of the wrench body 1 is pressed tightly. At this time, the shaft pin 2 can be positioned under the effect of the friction between the pressing button assembly 5 and the wrench body 1. When the wrench is subjected to excessive force, the force of the worm 7 is shared by the pressing button assembly 5, thereby achieving a protective effect on the worm 7 to avoid slippage;

[0039] When the wrench is used for a round-headed screwing piece, the main board lip 41 is pulled upward to disengage the square embedding block 43 from the square embedding groove. At this time, the rotation angle of the main board lip 41 is not limited. By rotating the main board lip 41, since the fixed plate lip 3 and the movable plate lip 4 have the same structure, the fixed plate lip 3 is subjected to the same operation. In this way, the inside and outside of the fixed plate lip 3 and the movable plate lip 4 can be swapped, so that the fixed plate lip 3 and the movable plate lip 4 have a V-groove surface as the clamping surface. When in use, the round-headed screwing piece is embedded in the V-groove of the fixed plate lip 3 and the movable plate lip 4, so as to increase the contact surface and increase the friction, thereby avoiding slipping when using the round-headed screwing piece.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. The utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model.
