Description

Technical Field

[0001] This utility model relates to the field of adjustable wrench technology, and in particular to an adjustable wrench with multiple locking positions for anti-slip operation. Background Technology

[0002] An adjustable wrench, also known as a sliding wrench, is a tool used to tighten and loosen nuts and bolts of different sizes, with its opening width adjustable within a certain range. An adjustable wrench consists of a head and a handle. The head comprises a sliding lip, a closed lip, a flange, a worm gear, and a pivot pin.

[0003] Most existing adjustable wrenches use a one-piece molded structure for the handle and the deadbolt lip. Therefore, when the deadbolt lip is worn, it is difficult to replace it separately, which increases the replacement cost. In view of this, we propose an adjustable wrench with multiple locking positions for anti-slip. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a multi-position adjustable anti-slip wrench to solve the technical problem that most existing adjustable wrenches use an integral molding structure for the handle and the fixed lip, so that when the fixed lip surface is worn, it is difficult to replace it separately, which increases the replacement cost.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: designing a multi-position adjustable anti-slip wrench, including a wrench body, wherein the wrench body is provided with several auxiliary components;

[0006] The wrench body includes a handle, the handle is covered with an anti-slip rubber pad, a positive and negative lead screw is provided above the handle, the surface of the positive and negative lead screw is covered with an upper lip and a lower lip, a set of guide rods are symmetrically fixed at the bottom of the upper lip, a limit block is fixedly connected to the bottom end of the positive and negative lead screw, a locking rod is fixedly connected to the lower end of the limit block, a screw is fixedly connected to the bottom end of the locking rod, and a hexagonal nut is covered on the outside of the screw.

[0007] Preferably, the upper plate lip, the lower plate lip, and the positive and negative lead screws are connected by threads. A set of guide grooves are symmetrically opened inside the lower plate lip. The upper plate lip and the lower plate lip form an engaging structure through the guide rod and the guide groove.

[0008] Preferably, the limiting block, the locking rod, and the screw are integrally formed, the limiting block is in the shape of an inverted frustum cone, and the combination of the limiting block and the locking rod is matched and engaged inside the handle.

[0009] Preferably, the auxiliary component includes a slot, which is formed inside the upper and lower plate lips. A locking block is engaged inside the slot, and an auxiliary plate is fixed to the surface of the locking block. A set of bolts is symmetrically engaged inside the locking block.

[0010] Preferably, the auxiliary plate forms an engaging structure with the upper and lower plates via a locking block and a locking slot, and the locking block forms a detachable structure with the upper and lower plates via bolts.

[0011] Preferably, a set of receiving grooves are symmetrically formed on the front and rear surfaces of the upper and lower plates, and the bolt head is entirely located in the receiving groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model effectively drives the forward and reverse screws to rotate by rotating the handle. At the same time, the guide rod and guide groove cooperate to guide and limit the movement. The distance between the upper and lower lip plates can be adjusted accordingly to accommodate different specifications of threaded fasteners. Since there are two clamping parts formed between the upper and lower lip plates, the adjustable wrench has a spare clamping part, which improves its practicality. Most of the components in the wrench body can be disassembled and separated, which facilitates subsequent partial replacement and reduces replacement costs.

[0014] 2. In this utility model, the auxiliary plate is used to contact the threaded fasteners that need to be tightened or loosened. When the auxiliary plate is worn, the disassembly bolt is used to release the restriction between the locking block and the upper and lower plates, making it easy to separate the locking block and the auxiliary plate from the upper and lower plates. Then, the replaced locking block and auxiliary plate are inserted into the slot and then limited by the bolt, which is quite convenient. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] Multi-position adjustable anti-slip wrench, see [link / reference] Figures 1 to 5 It includes a wrench body 1, and the wrench body 1 has several auxiliary components 2 inside;

[0025] The wrench body 1 includes a handle 101, with an anti-slip rubber pad 102 covering the outside of the handle 101. A positive and negative lead screw 103 is located above the handle 101. An upper lip 104 and a lower lip 105 are fitted onto the surface of the positive and negative lead screw 103. A set of guide rods 106 are symmetrically fixed to the bottom of the upper lip 104. The upper lip 104, the lower lip 105, and the positive and negative lead screw 103 are threaded together. A set of guide grooves are symmetrically formed inside the lower lip 105. The upper lip 104 is guided by the guide rods 106. 6. The guide groove and the lower plate lip 105 form a locking structure. The bottom end of the positive and negative lead screws 103 is fixed to a limiting block 107. The lower end of the limiting block 107 is fixed to a locking rod 108. The bottom end of the locking rod 108 is fixed to a screw 109. Furthermore, the limiting block 107, the locking rod 108, and the screw 109 are integrally formed. The limiting block 107 is in the shape of an inverted frustum. The combination of the limiting block 107 and the locking rod 108 is matched and locked inside the handle 101. A hexagonal nut 110 is sleeved on the outside of the screw 109. This utility model effectively drives the forward and reverse screws 103 to rotate by rotating the handle 101. At the same time, the guide rod 106 and the guide groove cooperate to guide and limit the movement. The distance between the upper lip 104 and the lower lip 105 can be adjusted accordingly to accommodate different specifications of threaded fasteners. Since there are two clamping parts formed between the upper lip 104 and the lower lip 105, the adjustable wrench has a spare clamping part, which improves its practicality. Most of the components in the wrench body 1 can be disassembled and separated, which facilitates subsequent partial replacement and reduces replacement costs.

[0026] It is worth noting that the auxiliary component 2 includes a slot 201, which is opened inside the upper lip 104 and the lower lip 105. A locking block 202 is engaged inside the slot 201, and an auxiliary plate 203 is fixed to the surface of the locking block 202. A set of bolts 204 are symmetrically engaged inside the locking block 202. The auxiliary plate 203 forms a locking structure with the upper lip 104 and the lower lip 105 through the locking block 202 and the slot 201. The locking block 202 forms a detachable structure with the upper lip 104 and the lower lip 105 through the bolts 204. Furthermore, a set of receiving grooves is symmetrically opened on the front and rear surfaces of the upper lip 104 and the lower lip 105, and the head of the bolt 204 is entirely located in the receiving groove. In this utility model, the auxiliary plate 203 is used to contact the threaded fasteners that need to be tightened or loosened. When the auxiliary plate 203 is worn, the disassembly bolt 204 is used to release the restriction between the locking block 202 and the upper plate lip 104 and the lower plate lip 105, so that the locking block 202 and the auxiliary plate 203 can be separated from the upper plate lip 104 and the lower plate lip 105. Then, the replaced locking block 202 and the auxiliary plate 203 are inserted into the slot 201 and then limited by the bolt 204, which is quite convenient.

[0027] Working principle: Rotating the handle 101 drives the forward and reverse lead screws 103 to rotate. Simultaneously, the guide rod 106 and guide groove provide guidance and limiting, allowing for adjustment of the distance between the upper lip 104 and lower lip 105. This facilitates the auxiliary plate 203's ability to clamp different specifications of threaded fasteners. Since there are two clamping points formed between the upper lip 104 and lower lip 105, the adjustable wrench has a spare clamping point, improving its practicality. Most components in the wrench body 1 are detachable. This facilitates subsequent partial replacement and reduces replacement costs. The auxiliary plate 203 is used to contact the threaded fasteners that need to be tightened or loosened. When the auxiliary plate 203 is worn, the disassembly bolt 204 is used to release the restriction between the locking block 202 and the upper plate lip 104 and the lower plate lip 105, thereby separating the locking block 202 and the auxiliary plate 203 from the upper plate lip 104 and the lower plate lip 105. Then, the replaced locking block 202 and the auxiliary plate 203 are inserted into the locking slot 201 and then limited by the bolt 204, which is quite convenient.
