Technical field
The utility model relates to field of power tools, especially a kind of Novel cylinder jacket.
Background technology
The cylinder sleeve that electric tool uses, its Main Function connects drill bit to drive drill bit high-speed rotation together with rotary drive mechanism with rotary drive mechanism, but in the use procedure of reality, the cylinder sleeve of current production is difficult to make drill bit and rotary drive mechanism have good interlock, often cause electric tool in use, one end is at High Rotation Speed, and other end turn up, less than requiring, causes electric tool cannot play its normal using function.And in the long-term High Rotation Speed of drill bit and impact process, probably cause the fracture of cylinder sleeve, affect the normal use of whole electric drill.
Summary of the invention
The purpose of this utility model provides a kind of not only interlock good and Novel cylinder jacket that is not easy fracture to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of Novel cylinder jacket designed by the utility model, comprise cylindrical body, described main body one end is connected with and coaxially arranges with main body and radius is less than the cylindric joint one of main body, described joint one is provided with cannelure one away from main body one end, cylindric joint one can stretch in rotary drive mechanism, gear can be arranged on cannelure one to be connected with rotary drive mechanism simultaneously, make the interlock that main body and rotary drive mechanism keep good, the described main body other end is connected with and coaxially arranges with main body and radius is less than the cylindrical connecting portion of main body, described connecting portion is connected with away from main body one end and coaxially arranges with main body and radius is less than the joint two of connecting portion, described joint two comprises coaxial setting and joint two top that increases gradually of radius, in the middle part of joint two and joint two bottom, described joint two bottom is connected with connecting portion, it is interior and fixing that drill bit can go deep into joint two,
Described main body periphery is provided with some grooves one arranged in the same way with main body, one end that described groove one one end is connected with joint one through main body, air-vent is provided with between adjacent groove one, described main body periphery is also provided with perpendicular with groove one and through the cannelure two of groove one, described cannelure two is near joint one, described groove one intersects with cannelure two, groove one is through main body one end simultaneously, thus the one end making main body be connected with joint one forms some boss, can improve the connective stability of main body and rotary drive mechanism;
Described main body is also provided with cannelure three and cannelure four, one end that described cannelure three is connected with connecting portion near main body, described cannelure four is near groove one, be provided with some through holes one that can be used for being pressed into steel ball between described cannelure three and cannelure four, press-in steel ball can make the connection of main body and drill bit more stable.
Further, in the middle part of described joint two, periphery is that indent circular arc is arranged, and is provided with some through holes two on the outer periphery, and through hole two can play the effect of better fixed drill bit, makes main body drive the rotation of drill bit, makes the interlock between cylinder sleeve main body and drill bit better.
Further, described main body, joint one, joint two and connecting portion are one-body molded, make its reliable in quality, not easy fracture.
A kind of Novel cylinder jacket that the utility model obtains, its technique effect is: in main body, arrange joint one, joint two one-body molded, better can connect the parts at two ends, substantially increase interlock, and entirety not easy fracture.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel cylinder jacket of the utility model.
Fig. 2 is the structure sectional view of a kind of Novel cylinder jacket of the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1-2, a kind of Novel cylinder jacket that the utility model provides, comprise cylindrical body 1, described main body 1 one end is connected with arrange and radius be less than the cylindric joint one 2 of main body 1 coaxial with main body 1, described joint 1 is provided with cannelure 1 away from main body 1 one end, cylindric joint 1 can stretch in rotary drive mechanism, gear can be arranged on cannelure 1 to be connected with rotary drive mechanism simultaneously, main body 1 and rotary drive mechanism is made to keep good interlock, described main body 1 other end is connected with arrange and radius be less than the cylindrical connecting portion 4 of main body 1 coaxial with main body 1, described connecting portion 4 is connected with arrange and radius be less than the joint two 5 of connecting portion 4 coaxial with main body 1 away from main body 1 one end, described joint 25 comprises coaxial setting and joint two top 6 that increases gradually of radius, in the middle part of joint two 7 and joint two bottom 8, described joint two bottom 8 is connected with connecting portion 4, it is interior and fixing that drill bit can go deep into joint 25,
Described main body 1 periphery is provided with some grooves 1 arranged in the same way with main body 1, one end that described groove 1 one end is connected with joint 1 through main body 1, air-vent 10 is provided with between adjacent groove 1, described main body 1 periphery is also provided with perpendicular with groove 1 and through the cannelure 2 11 of groove 1, described cannelure 2 11 is near joint 1, described groove 1 intersects with cannelure 2 11, groove 1 is through main body 1 one end simultaneously, thus the one end making main body 1 be connected with joint 1 forms some boss 12, the connective stability of main body 1 and rotary drive mechanism can be improved,
