Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

A kind of garden saw is arranged with detachable with the knife handle 2 as shown in Figure 1, including blade 1 and knife handle 2 outside blade 1 The protective case 3 of connection, protective case 3 are adapted with the shape size of blade 1.

The one side of protective case 3 is fixedly connected with the handle 31 that planform is in " U-shaped " setting.

It is fixedly connected between blade 1 and knife handle 2, knife handle 2 includes the interconnecting piece 21 of " concave shape ", and interconnecting piece 21 is far from " recessed The side of font " recess is fixedly connected with blade 1, and the both ends of 21 recess of " concave shape " interconnecting piece are fixedly connected with handle part 22.

As Figure 2-3, two parallel sides of its thickness direction of the set opening's edge of protective case 3 are concaved with limiting slot 42, The side that interconnecting piece 21 and 42 place protective case 3 of limiting slot fit sets to the concave fluted 4.

The locating part 41 being engaged by clamping with limiting slot 42 is equipped in two grooves 4, locating part 41 includes 411 He of wedge block Elastic component 412, elastic component 412 are spring；Spring one end is fixedly connected with wedge block 411, and the spring other end and 4 slot bottom of groove are solid Fixed connection；Wedge block 411 has wedge-shaped guide surface 413, and the direction of wedge-shaped guide surface 413 is arranged in knife handle 2 with protective case 3 It is contrary；The shape size of limiting slot 42 is adapted with wedge block 411.

Interconnecting piece 21 offers be connected to groove 4 two far from the one side of blade 1 about 21 central axis pair of interconnecting piece The sliding slot 5 of title.

The shifting part 51 being detached from for wedge block 411 and limiting slot 42 will to be corresponded to is equipped in each sliding slot 5；Shifting part 51 include connecting rod 511 and shifting block 512, and the planform of connecting rod 511 is arranged in " L shape ", and the radial cross-sectional shape of shifting block 512 is in " circle " setting, and the radial cross-sectional area of shifting block 512 is greater than the radial cross-sectional area of connecting rod 511；511 one end of connecting rod is pierced by recessed One side of the slot 4 with wedge block 411 close to 4 slot bottom of groove is fixedly connected, and 511 other end of connecting rod is pierced by sliding slot 5 and shifting block 512 is solid Fixed connection.

As in Figure 2-4, the side in each sliding slot 5 close to groove 4 is concaved with the first slot 6, the first slot 6 Radial cross-sectional shape is arranged in " circle ", and the side in each sliding slot 5 far from groove 4 is inwardly also recessed with the second slot 7, and second The radial cross-sectional shape of slot 7 is arranged in " circle ".

It is equipped in each sliding slot 5 and connect with shifting part 51 and be engaged by clamping with the first slot 6 or the second slot 7 and structure The plugging member 52 of the " T-shaped " setting of shape；Plugging member 52 includes the cross bar 521 and vertical bar 522 being arranged in a mutually vertical manner, cross bar 521 One end is fixedly connected with the middle part of vertical bar 522, and cross bar 521 is fixedly connected far from the one end at 522 middle part of vertical bar with connecting rod 511.

Vertical bar 522 is peripherally and outwardly convexly equipped with the first strip 61, edge in the first slot 6 along it close to one end of the first slot 6 Its circumferential direction is concaved with the first card slot 62 being engaged by clamping with the first strip 61.

Vertical bar 522 is peripherally and outwardly convexly equipped with the second strip 71, edge in the second slot 7 along it close to one end of the second slot 7 Its circumferential direction is concaved with the second card slot 72 being engaged by clamping with the second strip 71.

First strip 61 and the second strip 71 are that elastic material is made.

When protective case 3 is set on knife handle 2, wedge block 411 and limiting slot 42 are engaged by clamping, and spring is in nature elongation State, 522 one end of vertical bar are inserted into the first slot 6, and the first strip 61 and the first card slot 62 are clamped.

When protective case 3 and knife handle 2 are detached from, wedge block 411 and limiting slot 42 are detached from, and wedge block 411 returns to groove 4 Interior, spring is in compressive state, and one end of vertical bar 522 is inserted into the second slot 7 at this time, and the second strip 71 and the second card slot 72 block It connects, and the clamping power between the second strip 71 and the second card slot 72 is greater than elastic force when spring compresses at this time.

It the concrete operating principle of the present embodiment and has the beneficial effect that

Working principle:

When operating personnel does not use garden saw, protective case 3 is arranged from one end of blade 1 into knife handle 2,3 side of protective case Face squeezes the wedge-shaped guide surface 413 of wedge block 411, and wedge block 411 squeezes spring and moves to the direction of 4 slot bottom of groove, wedge block 411 are withdrawn completely into groove 4, and when 4 notch of groove is aligned with limiting slot 42, wedge block 411 is under the effect of spring force It is engaged by clamping towards the direction movement far from 4 slot bottom of groove and with limiting slot 42, the first strip 61 and the first card slot 62 are clamped at this time.

When operating personnel needs using garden saw, shifting block 512 is stirred first, and shifting block 512 drives connecting rod 511 and then drives The wedge block 411 being connected with connecting rod 511 is moved towards the direction close to 4 slot bottom of groove, and wedge block 411 squeezes spring, at this time vertical bar 522 one end are inserted into the second slot 7, and the second strip 71 and the second card slot 72 are clamped, due to the second strip 71 and the second card slot 72 Between elastic force of clamping power when being greater than spring-compressed, and then state " latching " of the wedge block 411 in groove 4, operating personnel Can win from blade 1 by protective case 3 by handle 31 can trim trunk and branch.

The utility model has the advantages that

It realizes that the installation between protective case 3 and knife handle 2 is fixed by the clamping between wedge block 411 and limiting slot 42, protects Blade 1 is arranged by sheath 3, is reduced blade 1 and is exposed to the outer injury for facing operating personnel, thus improves operating personnel Personal safety.

Due to the setting of shifting part 51, connecting rod 511 is driven to drive the wedge block 411 being attached thereto by shifting block 512 It is moved towards the direction close to 4 slot bottom of groove, squeezes spring, and then realize the disengaging between wedge block 411 and limiting slot 42, operation It is simple, convenient and fast.

Since when wedge block 411 and the clamping of limiting slot 42,522 one end of vertical bar and the first slot 6 are clamped, the first strip 61 It is engaged by clamping with the first card slot 62, further enhances the connective stability between wedge block 411 and limiting slot 42, and then reinforce Connective stability between protective case 3 and knife handle 2.

Since when wedge block 411 and the disengaging of limiting slot 42,522 one end of vertical bar and the second slot 7 are clamped, the second strip 71 It is engaged by clamping with the second card slot 72, elastic force when spring-compressed is greater than in the clamping between the second strip 71 and the second card slot 72, So that the state being detached between wedge block 411 and limiting slot 42 maintains, it is simple to operate quick.

It is convenient for operating personnel to be integrally hung on a wall garden saw by the setting of " U-shaped " handle 31, improves gardens The safety of saw, while operating personnel can also be detached from and install to protective case 3 by handle 31, it is simple to operate fast It is prompt.

It gets rusty, and then extends since the setting of protective case 3 plays protective effect to blade 2 and reduces 2 surface of blade The physical life of garden saw entirety, embodies environmentally protective theory.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
