Abstract

The utility model discloses a cylinder liner. The cylinder liner comprises a cylinder liner main body (1) and a chuck (2) arranged on one end of the cylinder liner main body (1), and is characterized in that the chuck (2) and the cylinder liner main body (1) are integrated. With the adoption of the above structure, the machining process is simplified, the chuck and the cylinder liner main body are directly formed in an integrative manner without respectively processing the chuck and the cylinder sleeve main body and then connecting both, so the strength and the fixing property of whole cylinder liner are enhanced, and the cylinder linier is hard to break in the service process so as to ensure the normal service of electric drills.

Description

Cylinder sleeve
Technical field
The utility model relates to the electric drill technical field, is specifically related to the cylinder sleeve that uses in a kind of electric drill.
Background technology
The cylinder sleeve that uses in the percussion drill comprises cylinder sleeve body and the chuck that is connected drill bit that is arranged at cylinder sleeve body one end.The chuck of prior art and cylinder sleeve body are to process respectively;, the cylinder sleeve body is provided with the semicircle hole slot that some footpaths concave on connecting the excircle of an end of chuck then; And on chuck and position that cylinder sleeve body semicircle orifice cooperates, be provided with some circular holes, realize being connected of cylinder sleeve body and chuck through die casting steel ball in circular hole.
But this cylinder sleeve body separates the structure made from chuck, can cause processing loaded down with trivial details, connects the insecure deficiency that waits, and probably causes the fracture between chuck and the cylinder sleeve body in long-term rotation at a high speed of drill bit and impact process, influences the normal use of whole electric drill.
The utility model content
The utility model provides a kind of sound construction, uses and stablize, not the cylinder sleeve of easy fracture to the above-mentioned deficiency of prior art.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cylinder sleeve, comprise the cylinder sleeve body, and be arranged at the chuck of cylinder sleeve body one end, it is characterized in that: described chuck and cylinder sleeve body are for being wholely set.
Adopt said structure, not only simplified procedure, need not process chuck and cylinder sleeve body respectively, again the two linked together; But the two direct one is processed; Increased the intensity and firm performance of whole cylinder sleeve, use is easy fracture not, guarantees the normal use of electric drill.
Description of drawings
The structural representation of accompanying drawing the utility model cylinder sleeve.
As shown in the figure: 1. cylinder sleeve body, 2. chuck.
The specific embodiment
Through embodiment the utility model is described in further detail below.
Shown in accompanying drawing, this practical new a kind of cylinder sleeve comprises cylinder sleeve body 1, is arranged at the chuck 2 of cylinder sleeve body 1 one ends, it is characterized in that: described chuck 2 and cylinder sleeve body 1 are for being wholely set.
Adopt said structure, not only simplified procedure, need not process chuck 2 and cylinder sleeve body 1 respectively, again the two linked together; But the two direct one is processed; Increased the intensity and firm performance of whole cylinder sleeve, use is easy fracture not, guarantees the normal use of electric drill.

Claims (1)
