Abstract

The woodworking clamp used in the narrow space comprises a rhombic clamping block, a main body, a pin and a spring, the main body is divided into a left part and a right part, the left part and the right part are hinged through the pin, and the spring used for providing restoring force is arranged in the pin. The front ends of the left part and the right part of the main body are respectively provided with a rhombic clamping block used in a limited narrow space. The front arms of the left clamp body and the right clamp body are designed to be in a slender equilateral inclination shape, and therefore the clamp can stretch into a narrow client to clamp a workpiece. The head of the clamp is provided with two small rhombic clamping blocks which are narrower than the head of the left clamp body and the head of the right clamp body, so that the clamp is more suitable for being inserted into a small groove and small-sized manual manufacturing, is suitable for bonding, maintaining and processing small-sized woodworking pieces and is used in limited narrow space.

Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of clamp, especially relates to a woodworking clamp used in narrow space. BACKGROUND

[0002] Clamp refers to the device used for fixing the machining object in the mechanical manufacturing process, making it occupy the correct position to accept construction or detection, also called fixture. In a broad sense, in the process of any process, the device used for quickly, conveniently and safely installing workpiece can be called clamp.

[0003] Clamp is usually composed of positioning element (determining the correct position of workpiece in clamp), clamping device, guide element (determining the relative position of tool and workpiece or guiding tool direction), indexing device (making workpiece complete several workstations in one installation, including rotary indexing device and linear movement indexing device), connecting element and clamp body (clamp base) etc.

[0004] The structure of the existing spring clamp: the head of left and right clamping bodies is very wide, and the clamping block is very wide, so it cannot clamp woodworking workpiece for processing in narrow space and specific space with small groove. SUMMARY

[0005] In order to make up for the deficiency of the prior art, the woodworking clamp used in narrow space is provided to solve the problems in the prior art.

[0006] In order to solve the above technical problems, the utility model provides the following technical scheme:

[0007] A woodworking clamp used in narrow space, comprising a rhombic clamping block, a main body, a pin and a spring, the main body is divided into left and right parts, the left and right parts are hinged through the pin, the pin is internally provided with a spring for providing restoring force, and the left and right parts of the main body are provided with rhombic clamping blocks at the front ends for use in limited narrow space.

[0008] As a further technical scheme of the utility model: the spring is a V-shaped spring, which is opened by being extruded.

[0009] As a further technical scheme of the utility model: the contact surface of the rhombic clamping block is provided with a tooth groove for increasing the friction coefficient.

[0010] One or more technical schemes provided in the embodiment of the application have at least the following technical effects or advantages:

[0011] This invention features a slender, equilateral beveled forearm design for the left and right clamping bodies, which facilitates the clamping of workpieces in narrow spaces. The two small, rhomboid clamping blocks at the clamping head are narrower than the heads of the left and right clamping bodies, making them more suitable for inserting into small grooves and for small-scale handcrafting. This design is ideal for gluing and repairing small wooden workpieces in confined, narrow spaces. Attached Figure Description

[0012] Figure 1 This is a structural diagram of the present invention.

[0013] Figure 2 This is a schematic diagram of the operation of Embodiment 1 of this utility model.

[0014] Figure 3 This is a schematic diagram of the second embodiment of this utility model.

[0015] Figure 4 This is a schematic diagram of the operation of Embodiment 3 of this utility model.

[0016] In the diagram: Clamping block-1, main body-2, pin-3, spring-4. Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1 As shown, a woodworking clamp for use in confined spaces includes a diamond-shaped clamping block 1, a main body 2, a pin 3, and a spring 4. The main body 2 is divided into left and right parts, which are hinged together by the pin 3. The pin 3 contains a spring 4 to provide restoring force. Both the left and right ends of the main body 2 are provided with diamond-shaped clamping blocks 1 for use in confined spaces. As a further technical solution of this utility model: the spring 4 is a V-shaped spring, which opens the main body 2 when compressed.

[0019] The working principle is as follows:

[0020] The technical solution of this utility model is that by squeezing the left and right main bodies 2 with one hand, the V-shaped spring 4 is squeezed and the front clamping block 2 is opened. The slender forearm of the main body 2 and the diamond-shaped clamping block with a width smaller than the width of the clamp can easily clamp the groove of the workpiece and the upper and lower planes of small workpieces to complete the clamping work.

[0021] The V-shaped spring structure in the clamp is specially designed, the clamp and separation can be completed by one hand, the opening size is larger, the workpiece of larger size can be clamped, the V-shaped spring elasticity is larger, more than 30% of the conventional clamp force, and the clamping is more stable.

[0022] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.

[0023] In addition, it should be understood that, although the present application is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment have been properly combined to form other embodiments which are easily understood by those skilled in the art.
