As preferably, described first connecting rod is connected with insulated tension pole away from an end of described first drive rod.
As preferably, described first coupler body has the first relative arc clamping face and the second arc clamping face respectively with second coupler body.
As preferably, the described first arc clamping face and the second arc clamping face have sawtooth.
As preferably, offer the first hinged installing hole of at least one and described first connecting rod on described first drive rod; Offer the second hinged installing hole of at least one and described second connecting rod on described second drive rod.
As preferably, described head rod is provided with for auxiliary described clamping device clamping, the fixing and draw ring that pulls held object.
Compared with prior art, the beneficial effect of clamping device of the present utility model is: by the first operation hook and the second operation hook that has sawtooth, and with first connecting rod and second connecting rod articulated structure flexibly, the trees of firmly promptly will cut down, pruning, greatly reduce tree hook slippage number of times, realize cutting down, prune critical trees fast, reduced climbing trees personnel's security risk.

The specific embodiment
Describe in further detail below in conjunction with the clamping device of the drawings and specific embodiments to embodiment of the present utility model, but not as to restriction of the present utility model.
Fig. 1 is the overall structure schematic diagram of the clamping device of embodiment of the present utility model; Fig. 2 be embodiment of the present utility model clamping device first the operation hook structural representation; Fig. 3 be embodiment of the present utility model clamping device second the operation hook structural representation; Fig. 4 is the use status architecture schematic diagram of the clamping device of embodiment of the present utility model.As shown in the figure, the clamping device of embodiment of the present utility model, be used for clamping, fix and pull held object, held object can make trees etc., comprise the first operation hook 1 and the second operation hook 2 that are hinged, the first operation hook 1 comprises that first coupler body 11 of front end and first drive rod, 12, the second operation hooks 2 of rear end comprise second coupler body 21 of front end and second drive rod 22 of rear end; First drive rod 12 is hinged with first connecting rod 3, the second drive rods 22 and is hinged with second connecting rod 4; First connecting rod 3 and second connecting rod 4 are hinged and make described first drive rod 11, second drive rod 12, first connecting rod 3 and second connecting rod 4 form quadrangle.During use, win coupler body 11 and 12 lockings of second coupler body with gripped objects such as clamping trees by pulling first connecting rod 3, utilizing lever principle to make.The clamping device of embodiment of the present utility model, by the first operation hook 1 and the second operation hook 2, and with first connecting rod 3 and second connecting rod 4 articulated structure flexibly, the trees of firmly promptly will cut down, pruning, greatly reduce tree hook slippage number of times, realize cutting down, prune critical trees fast, reduced climbing trees personnel's security risk.
As a kind of improvement, the first connecting rod 3 of the clamping device of embodiment of the present utility model is connected with insulated tension pole 5 away from an end of first drive rod 12.Practical operation because the transmission overhead line operation belongs to altitude hot-line operation, can be operated safe and convenient easily by insulated tension pole 5 is set to the eminence object.
