Description

Hand-held type multifunctional saw Protective lock device

Technical field

The utility model relates to a kind of safety device, particularly the self-locking protecting device of the anti-unexpected cutting of a kind of hand-held type multifunctional saw.

Background technology

Hand-held type multifunctional saw is a kind ofly to take series machine as power, by transmission mechanism, drive the cutting tool of saw blade sawing operation, mainly take cutting timber and building, finishing section bar as main, have that volume is little, lightweight, cutting efficiency is high, portably use the features such as convenient, not only greatly reduce operator's labour intensity, and improved operating efficiency, extremely users' welcome, is widely used in all trades and professions.But there is the problems such as protector validity is not good enough in the hand-held type multifunctional using at present saw, when machine run, saw blade High Rotation Speed, touches unintentionally saw blade and cause sometimes huge property loss, and can produce injury to human body.For fear of the generation of misoperation, people have proposed a lot of safety approach, still have irrational place and unsafe factor.For the problems referred to above, many manufacturers and knowledgeable people have carried out development, but not yet have so far the comparatively ideal product of formation to emerge.

Summary of the invention

For overcoming existing hand-held type multifunctional saw above shortcomings, the purpose of this utility model is to provide a kind of hand-held type multifunctional simple and reasonable, easy for operation, that operating efficiency is high, safe and reliable and saws Protective lock device.

The utility model solves the problems of the technologies described above adopted technical scheme, comprise handle, body, base plate, head capsule, switch, switch is arranged on the handshake part of handle, in the handshake part of described handle, be hinged with trigger, the connecting portion of handle is provided with the pushing block that can slide up and down, pushing block is provided with stage clip, stage clip one end withstands on pushing block, the other end is fixed in the draw-in groove of handle, on head capsule, be hinged with protection locking plate, backer is installed on base plate, backer is provided with guide groove, pushing block inside is inserted in protection locking plate one end, the protection locking plate other end does not intersect in locking configuration state with backer's end face when pressing trigger, when pressing trigger, rotate a theta alignment backer's guide groove in released state.

The further scheme of the utility model, described backer's guide groove is provided with degree of depth limited block that can up-down adjustment, and degree of depth limited block is fixedly connected with backer by depth adjustment knob.

Adopt after said structure, compared with prior art have the following advantages and effect: during work, press cocking after switch connection power supply, trigger drives protection locking plate to rotate an angle by pushing block, protection locking plate forwards backer's guide groove position to from backer's end face, reach the object of release, make to protect locking plate and can move up and down along backer's guide groove in sawing process; After sawing completes, when trip switch and trigger, trigger and pushing block automatically reset under the elastic force effect of stage clip, and pushing block drives protection locking plate reset and intersected self-locking with backer's end face simultaneously; Simple and reasonable, easy to operate, safe and reliable, can avoid the generation of unexpected triggering accident, greatly improved the safety coefficient that product is used.

Accompanying drawing explanation

The structural representation of another side when Fig. 2 is the utility model lock configuration state.

Structural representation when Fig. 3 is the utility model released state.

The structural representation of another side when Fig. 4 is the utility model released state.

Wherein, 1 switch, 2 handles, 3 triggers, 4 bodies, 5 stage clips, 6 pushing blocks, 7 protection locking plates, 8 depth adjustment knobs, 9 backers, 10 base plates, 11 head capsules, 12 degree of depth limited blocks.

The specific embodiment

Shown in Fig. 1 to Fig. 4, specific embodiments for a kind of hand-held type multifunctional saw of the utility model Protective lock device, it comprises handle 2, body 4, base plate 10, head capsule 11, switch 1, switch 1 is arranged on the handshake part of handle 2, in the handshake part of described handle 2, be hinged with trigger 3, the connecting portion of handle 2 is provided with the pushing block 6 that can slide up and down, pushing block 6 is provided with stage clip 5, stage clip 5 one end withstand on pushing block 6, the other end is fixed in the draw-in groove of handle 2, on head capsule 11, be hinged with protection locking plate 7, backer 9 is installed on base plate 10, backer 9 is provided with guide groove, pushing block 6 inside are inserted in protection locking plate 7 one end, protection locking plate 7 other ends do not intersect in locking configuration state with backer 9 end face when pressing trigger 3, when pressing trigger 3, rotate a theta alignment backer's 9 guide groove in released state.

During the utility model work, cocking 3 after pressing switch 1 and switching on power, jointed shaft on the thorny handle 2 of trigger 3 rotates, its other end pushes up downwards presses pushing block 6, after the elastic force that overcomes stage clip 5, promote pushing block 6 and move down, pushing block 6 drives protection locking plate 7 to rotate an angle, and protection locking plate 7 forwards backer 9 guide groove position to from backer 9 top machine, reach the object of release, make to protect locking plate 7 and can move up and down along backer 9 guide groove in sawing process.After sawing completes when trip switch 1 and trigger 3, trigger 3 and pushing block 6 automatically reset under the elastic force effect of stage clip 5, pushing block 6 drives protection locking plate 7 to rotate an angle simultaneously, the free end of protection locking plate 7 forwards backer 9 end face in backer 9 guide groove, and has intersected self-locking with the end face on backer 9.

In order to reach the object that regulates depth of cut, described backer's 9 guide groove is provided with degree of depth limited block 12 that can up-down adjustment, degree of depth limited block 12 is fixedly connected with backer 9 by depth adjustment knob 8, and when cutting puts in place, the free end of protection locking plate 7 is subject to stopping of degree of depth limited block 12.

The above is specific embodiment of the utility model; not the utility model is made to any pro forma restriction; do not departing from the technical solution of the utility model basis, the simple modification of having done, equivalent variations or modification, all fall into protection domain of the present utility model.
