Abstract
The invention discloses a machine head rebounding device which comprises a machine body, a machine head and a compressed spring. The machine body is provided with a machine body support, and a locating pin is mounted on the machine body support. The machine head is provided with a sleeve where the compressed spring can be placed, and the top of the compressed spring makes contact with the inner wall of the upper portion of the sleeve and is fixed in the sleeve through a fixing device. The bottom of the compressed spring is provided with a compressed spring fixing base, and the bottom of the compressed spring fixing base can make full contact with the contact surface of the locating pin through extrusion on the compressed spring. According to the machine head rebounding device, since a common torsion spring is replaced by the compressed spring to rebound the machine head, and the structure of the machine body and the structure of the machine head are adaptively improved, the machine head can be rebounded in place more easily, that is the compressed spring can rebound more easily than the torsion spring do when the machine head is pressed downward to a certain position and external force is removed by loosening both hands.
Description
Technical field
The present invention relates to a kind of electric cutting tool, be specifically related to a kind of resilient mounting of electric cutting tool.
Background technology
At present, electric cutting tool is widely used in machining and manufacture field.Diagonal cutting saw is one of the most common electric cutting tool.Diagonal cutting saw comprises head and body, in use, in the time of need to cutting workpiece, as long as press down head, can drive saw blade to cut workpiece; After cutting, head resilience.Diagonal cutting saw of the prior art, generally adopts torsion spring to make head resilience, and torsion spring is to rely on its torsional elasticity to produce frictional force with the spring of transferring power or motion.So, adopt torsion spring to make head resilience, conventionally also to, by external force, to operation, make troubles.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of than the more easy head resilient mounting more easily of torsion spring resilience.
Technical scheme: for solving the problems of the technologies described above, head resilient mounting of the present invention comprises body, head and stage clip, described body is provided with body and supports, and body is provided with alignment pin on supporting; Described head is provided with for placing the sleeve of stage clip, the top of described stage clip contacts with the inwall of upper cartridge, adopt fixture that stage clip top is fixed in sleeve, the bottom of stage clip is provided with stage clip holder, by extruding stage clip, makes the bottom of stage clip holder and the contact-making surface of alignment pin for contacting completely.
Wherein, described fixture comprises pressing plate and for the hex screw of fixation clip.
Stage clip, it is the helical spring bearing to pressure, because bearing pressure, two ends can be open type or enclosed or around flat or polish, that its material section used mostly is is circular, also useful rectangle and multiply steel are entangled and rolled, and spring has equal pitch and pitches, the shape of Compress Spring has: the variant of cylindrical, conical, camber and middle concave and a small amount of non-circular and even various tail end, and all can be according to product needed according to design moulding.Between the circle of stage clip and circle, have certain gap, when being subject to external applied load, spring contraction distortion, stores deformation energy.
Beneficial effect: head resilient mounting of the present invention, by adopting stage clip to replace conventional torsion spring to make head resilience, and the structure of body and head is carried out to adaptive improvement, head resilience is more easily put in place: when head is depressed into certain position, unclamp both hands, remove external force, the resilience of stage clip is easier than the resilience of torsion spring, easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, head resilient mounting of the present invention comprises body 2, head 1 and stage clip 6, and described body 2 is provided with body and supports 3, and body supports on 3 alignment pin 4 is installed; Described head 1 is provided with for placing the sleeve 5 of stage clip 6, the top of described stage clip 6 contacts with the inwall on sleeve 5 tops, adopt fixture that stage clip 6 tops are fixed in sleeve 5, the bottom of stage clip 6 is provided with stage clip holder 7, by extruding stage clip 6, make the bottom of stage clip holder 7 and the contact-making surface of alignment pin 4 for contacting completely, be called again full contact.Wherein, described fixture comprises pressing plate 8 and for the hex screw 9 of fixation clip 8.Stage clip 6 in the present embodiment is cylindrical stage clip.
The present invention in use, when head 1 is depressed into certain position, unclamps both hands, removes external force, and the resilience of stage clip 6 is easier than the resilience of torsion spring, easily.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
