Abstract
Description
Technical Field
[0001] The utility model relates to a telescopic saw, and more particularly to a telescopic saw. Background Art
[0002] A manual telescopic saw, also often called a reciprocating saw or telescopic hacksaw, is a manually operated tool whose main feature is the retractable and adjustable blade. A manual telescopic saw is a tool that uses manual force to drive a reciprocating saw blade to cut a variety of materials. The blade can be adjusted to fit materials of varying lengths and thicknesses.
[0003] The blade of an existing manual telescopic saw is secured with a set screw during extension and retraction. Due to the smooth surface of the handle, the saw will vibrate during the sawing process. If the handle is smooth, this vibration is more easily transmitted through the handle to the set screw, causing the set screw to become undertightened or loose, which in turn causes the saw blade to loosen, increasing safety risks during use.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0005] In response to the shortcomings of the prior art, the purpose of the present invention is to provide a telescopic saw. By providing a frosted layer and a rubber sleeve on the outer surface of the handle, the tool will generate a certain amount of vibration during operations such as sawing. The rubber sleeve has a certain shock-absorbing effect, which can absorb and reduce the impact of these vibrations on the handle and the positioning bolt. By reducing the transmission of vibration, the rubber sleeve helps to maintain the tight state between the positioning bolt and the handle, reducing the risk of loosening due to vibration. By providing a frosted layer with a certain degree of roughness, the static friction between the frosted layer and the positioning bolt is increased. When the user rotates the positioning bolt to tighten it, this increased friction allows the user to apply force more stably, thereby improving the tightening force of the positioning bolt, improving the tightening force of the positioning bolt, preventing loosening, and ensuring safety during the use of the telescopic saw.
[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a telescopic saw, comprising a handle and a saw blade, the saw blade being movably inserted and connected to the left side of the handle, a groove being provided on the front side of the handle, a frosted layer being fixedly installed on the outer surface of the handle, a rubber sleeve being fixedly installed on the right side of the outer surface of the handle, a positioning bolt being movably connected to the front side of the handle, and the positioning bolt passing through the groove and being movably threadedly connected to the side of the saw blade.
[0007] The utility model is further configured as follows: a through slot is provided at the right end of the handle.
[0008] The utility model is further configured as follows: the handle and the saw blade are both configured in an arc shape.
[0009] The utility model is further configured as follows: an arc-shaped block is fixedly installed on the left side of the outer surface of the handle.
[0010] The utility model is further configured as follows: a limit hook is fixedly installed on the right end of the handle.
[0011] In summary, the present invention has the following beneficial effects:
[0012] 1. By providing a frosted layer and a rubber sleeve on the outer surface of the handle, the tool will generate a certain amount of vibration during operations such as sawing. The rubber sleeve has a certain shock-absorbing effect, which can absorb and reduce the impact of these vibrations on the handle and the positioning bolt. By reducing the transmission of vibration, the rubber sleeve helps to maintain the tight state between the positioning bolt and the handle, reducing the risk of loosening due to vibration. By providing a frosted layer with a certain degree of roughness, the static friction between the frosted layer and the positioning bolt is increased. When the user rotates the positioning bolt to tighten it, this increased friction allows the user to apply force more stably, thereby improving the tightening force of the positioning bolt, improving the tightening force of the positioning bolt, preventing loosening, and then preventing the saw blade from loosening, ensuring safety during the use of the telescopic saw.

[0019] The present invention will be described in detail below with reference to the accompanying drawings.
[0020] A telescopic saw, such as Figures 1 to 2 As shown, the saw blade 2 includes a handle 1 and a saw blade 2. Both handle 1 and blade 2 are arranged in an arc shape. The saw blade 2 is movably connected to the left side of the handle 1. A groove 3 is defined on the front side of the handle 1. A frosted layer 4 is fixedly mounted on the outer surface of the handle 1. A rubber sleeve 5 is fixedly mounted on the right side of the outer surface of the handle 1. A positioning bolt 6 is movably connected to the front side of the handle 1. The positioning bolt 6 passes through the groove 3 and is movably threadedly connected to the side of the saw blade 2. A through slot 7 is defined on the right end of the handle 1. An arc-shaped block 8 is fixedly mounted on the left side of the outer surface of the handle 1. The frosted layer 4 and rubber sleeve 5 on the outer surface of the handle 1 prevent the tool from vibrating during sawing operations. The rubber sleeve 5 has a certain shock-absorbing effect, absorbing and reducing the impact of these vibrations on the handle 1 and the positioning bolt 6. By reducing vibration transmission, the rubber sleeve 5 helps maintain the tightness between the positioning bolt 6 and the handle 1, reducing the risk of loosening due to vibration. The frosted layer 4 has a certain degree of roughness, which increases the static friction between the frosted layer 4 and the positioning bolt 6. When the user rotates the positioning bolt 6 to tighten it, the increased friction enables the user to apply force more stably, thereby improving the tightening force of the positioning bolt 6, improving the tightening force of the positioning bolt 6, preventing loosening, and ensuring safety during the use of the telescopic saw.
[0021] like Figure 2 As shown, a limit hook 9 is fixedly installed on the right end of the handle 1. The limit hook 9 can effectively fix the saw blade 2 to prevent the saw blade 2 from deflecting or falling off due to uneven force or vibration during the sawing process, thereby improving the stability and safety of sawing.
[0022] Working Principle: By providing a frosted layer 4 and a rubber sleeve 5 on the outer surface of the handle 1, the tool generates a certain amount of vibration during sawing operations. The rubber sleeve 5 has a certain shock-absorbing effect, absorbing and reducing the impact of these vibrations on the handle 1 and the retaining bolt 6. By reducing the transmission of vibration, the rubber sleeve 5 helps maintain the tightness between the retaining bolt 6 and the handle 1, reducing the risk of loosening caused by vibration. The frosted layer 4 has a certain degree of roughness, which increases the static friction between the retaining bolt 6 and the handle 1. When the user rotates the retaining bolt 6 to tighten it, this increased friction allows the user to apply force more steadily, thereby improving the tightening force of the retaining bolt 6, preventing loosening. This, in turn, prevents loosening of the saw blade 2 and ensures safety during telescopic saw use. When the saw blade 2 is in use, the retaining bolt 6 is pushed, causing it to move within the slot 3, completing the retraction of the saw blade 2 within the handle 1.
